Installing GnuPG from Source on Docker Image Fails to Find Dependent Libraries

Installing Gnupg and its dependent libraries from source on the AWS Lambda Docker image public.ecr.aws/lambda/python:3.9, fails due to the libraries being undetected with the error: error while loading shared libraries: libgcrypt.so.20: cannot open shared object file: No such file or directory

Doing a default installation of the libraries was successful, but when I went to install Gnupg do the default path, the make check fails all of the tests with the following error

Attempting to set the configure prefix to /usr allowed me to install libgpg-error with no issue but attempting to install libgcrypt, it fails to do the make command due to a undefined refference to GPG_ERROR

GPG Decryption Error: GPG Keys From GnuPG V2.3 Not Recognized in GnuPG V2.2

A customer support ticket was opened in which an issue occurred where the PGP Decryption Lambda encountering a decryption error.

Upon further investigation, we have discovered that the base images are using outdated versions of GnuPG which do not recognize GPG keys that were generated in GnuPG version 2.3 and newer.

According to the GnuPG New File, version 2.3.0 was released in 2021-04-07 and changed the way that GPG keys were generated. As a result any version of GnuPG below version 2.2.28 would not recognize a key generated in version 2.3+.

For the base images in this project, Google used GnuPG version 2.2.4, for AWS 2.0.22, and in Azure 2.2.12. For this reason GnuPG needs to be updated for each cloud provider.
